CBS is down 0.9% this morning at $49.97, despite the company topping expectations in the earnings confessional last night. Wall Street weighed in on the news, with Pivotal Research upgrading the stock's rating to "buy" from "hold," and Macquarie cutting its price target to $62 from $68. Technically speaking, CBS Corporation has been pressured lower in recent months by its descending 20-day moving average -- including yesterday's sector-related 4.6% drop. Nonetheless, the brokerage bunch is extremely upbeat, with 15 of 18 analysts handing out "buy" or better endorsements -- with not a single "sell" to be found. What's more, CBS' average 12-month price target of $65.90 sits in annual-high territory.

GMCR is collapsing this morning, due to lower-than-expected quarterly revenue -- exacerbated by steep declines in coffee maker sales. The company also announced an upcoming round of job cuts.The brokerage bunch is pouncing on the news, with Canaccord Genuity, Morgan Stanley, Susquehanna, and Goldman Sachs all lowering their ratings -- with the latter removing Keurig Green Mountain Inc from its "America's Buy" list. Those four firms -- along with at least five others -- cut their price targets, too. Out of the gate, GMCR has plunged about 27% at $54.53, and panned a two-year low of $52.40 earlier. Short sellers are likely cheering the bear gap. Over one-tenth of the stock's float is sold short, representing more than seven days' worth of trading, at typical volumes. Suffice it to say, GMCR has not lived up to its historical August outperformance.

ZUMZ hit an annual low of $22.90 this morning, and was last seen 9.1% south of breakeven at $23.14, thanks to a sharp decline in July same-store sales and a downbeat second-quarter profit forecast. So far in 2015, in fact, the shares have surrendered roughly 40%. On the sentiment front, at least four brokerage firms slashed their price targets, with the lowest bar set by Wedbush, at $22 -- territory not charted since February 2014. Short sellers are skeptical of Zumiez Inc., as well. During the last two reporting periods, short interest soared 39.4%, and now accounts for 14% of the equity's total float. At ZUMZ's typical trading levels, it would take roughly nine sessions to repurchase all these bearish bets.
